JerryPhotoNatural Disasters! The phrase that evokes fear in all of us. We have just gone through the experience of the deadly earthquake and tsunami in northern Japan. The expected loss of life is expected to be 18,000 or more. And that doesn’t factor in those who will become sick and die from the radiation leaks from the damaged nuclear power stations. On the whole, this is the largest disaster in decades.

But let us not forget the earthquake that hit the Anchorage area of Alaska in 1964. This quake was about the same magnitude as that in Japan. It also hit in a subduction zone, a necessary condition for generating a massive tsunami. After the winter ice, the Port of Valdez was once again open to tanker traffic. The first tanker was tied to the pier on this day, but after the quake, the water of the port receded, sucking the ship into its votex, with all personnel aboard. Then the 30 foot tsunami wave hit with such force that the buildings came down, the debris was then sucked out to sea.


The death toll of the Alaska quake was low. Due to the sparsely-settled coastal areas, only 131 lives were lost. But property damage was extensive. We have just seen what a similar quake and tsunami would do in a more populated area. And in Japan we saw the disaster hit in real-time. This was a natural disaster that will remain embedded in our minds for many years to come.

So, let’s start our exploration of the Alaskan Earthquake and its mechanics…  GLB

JerryPhotoI sat in awe as I watched the Tsunami the hit Sendai, Japan, today. To see that thirty foot high wall of water rushing over the countryside taking houses, trains, cars and any other obstacle out as it progressed. Here in Southern California we live with earthquakes of 6.0 + range, but the quake that generated today’s tsunami was an 8.9, about a thousand times more powerful than the largest one that I remember (an 7.1).

The area that generated this tsunami was about 150 miles by 500 miles in size — larger than anything that I have ever thought of. I remember seeing History Channel programs about the Dam Buster raids in the Ruhr valley during World War II. I also remember seeing the sequence in the movie, “Force 10 from Navarone,” that used the force of water from a “blown” dam to destroy a bridge that could not be taken down by explosives. Such is the power of water!


The current post presents some basic facts about tsunamis for your understanding. I have included an excerpt from a Washington Post article as well as a short video of the event. Let us remember the victims and survivors of this tragedy in our prayers… GLB
